IMPROVEMENT IN REFLECTORS.

Specification forming part of Letters Patent N 0. 167,187, dated August31, 1875; application filed May 7, 1874.

To all whom it may concern:

Be it known that I, GHAUNOEY M. MURCH, of Cincinnati, in the county ofHamilton and State of Ohio, have invented a new and useful Improvementin Reflectors for Lamps, of which the following is a specification:

The subject of this invention is a reflector pierced to fit over thechimney of an- Argand or other burner, and suspended from the top ofsaid chimney by a hooked rod in such a way as to be capable of verticaland rotary adjustment.

The accompanying drawings are vertical sections, showing the reflectorin two positions, the chimney being represented in elevation.

E represents a parabolic reflector fitting over the cylindrical chimneyO, and suspended from the top thereof by a rod, P, formed at its upperend with a book, 1), and at its lower end with a screw-thread, 10,receiving a thumb nut, Q, affording vertical adjustment to any necessaryextent.

The mode of attachment will also be seen to admit of rotary adjustmentor turning the reflector round, so as to present it in any direction.

The chimney can be passed through one opening in the reflector, as inFig. 1, so as to throw the light downward for use in reading or writing,concentrating it on one side of the lamp in the most advantageous manneror the chimney may be passed through two openings, as in Fig. 2, thelight being then thrown in a nearly horizontal path.

I am aware that reflectors have before been suspended fromlamp-chimneys, and made capable of both vertical and lateral adjustment.This, therefore, I do not broadly claim; but

What I do claim, and desire to secure by Letters Patent, is-

The combination of the parabolic reflector E, capable of being placed onthe chimney in either a nearly vertical or nearly horizontal position,the hool; p, threaded wire P, and thumb-nut Q, all as herein shown anddescribed.
